[PVE-User] Migrating a vmdk from NAS to LVM

[Dhaussy Alexandre]

Hello,

I'm trying to "storage move" disks from NFS/vmdk to LVM/raw.
But it doesn't seems to work within proxmox GUI.

Here's the error message:

##########################

Task viewer: VM 410 - Move disk

Is seems qemu complains about "output file is smaller than input file".

Anyway i tried to add a new LVM disk from the GUI (41Gb: same size as 
the original.)
After that i was able to convert the disk succesfully !

root at proxmox:# /usr/bin/qemu-img convert -t writeback -p -n -f vmdk -O 
raw /nas/proxmox/images/410/vm-410-disk-1.vmdk 
/dev/T_proxmox_1/vm-410-disk-1
     (100.00/100%)

Cheers,
Alexandre.
